Abstract (en)

[origin: WO02073073A1] An intercept valve for fluids, comprising a tubular element (2) made of a deformable material, which internally defines a passage provided with an inlet (3) and an outlet (4) for a fluid to be intercepted. The tubular element (2) is housed internally of a second tubular element (5) made of steel and having an inlet (7) through which, on command, a pressurised fluid is introduced which closes the passage by laterally choking the tubular element (2). In an open configuration, a median section of the tubular element (2), which is choked to close the tubular element (2), is slightly pre-choked in a preferred choking direction and is free to expand in a direction which is transversal to the preferred choking direction. The valve guarantees a sealed closure. The valve can be used in particular in a device for filling containers with a liquid product.
